When used as a diacritic mark, the term dot is usually reserved for the Interpunct ( · ), or to the glyphs 'combining dot above' ( ◌̇ ) and 'combining dot below' ( ◌̣ ) which may be combined with some letters of the extended Latin alphabets in use in Central European languages and Vietnamese.

Overdot[edit]

Language scripts or transcription schemes that use the dot above a letter as a diacritical mark:

The overdot is also used in the Devanagari script, where it is called anusvara.

However, today this is more commonly written with a prime or using Leibniz's notation.[citation needed] In addition, the overdot is one way used to indicate an infinitely repeating set of numbers in decimal notation, as in , which is equal to the fraction 13, and or , which is equal to 17.

Underdot[edit]

The underdot is also used in the Devanagari script, where it is called nukta.
